JOHN S. M. WILLCOX, OF WHITBY, ONTARIO, CANADA.

PUMP.

SPECIFICATION forming part of Letters Patent No. 236,745, dated January 18, 1881.

Application filed November 10, 12580.

To all whom it may concern:

Be it known that I, JOHN S. M. WILLGOX, of

WVhitby, in the Province of Ontario and Do= ings, which form a part of this specification.

Figure 1 is a vertical sectional view of a pump embodying my improvements; and Fig. 2 is a detail view of the piston-rod and pulley.

This invention relates to pumps; and it consists in the improved features of construction and combination hereinafter fully described, and particularly pointed out in the claim.

Referring by letter to the accompanying drawings, A designates a pulley, of wood or iron, at the upper end of the pump-handle. B designates the piston rod. 0 designates a chain, rope, or wire attached to a staple, J, in the piston-rod B, and passed over the upper surface of the pulley A through the slot G; thence around the under surface of the pulley, and made fast to a bolt at the upper end of the piston-rod. D designates the pump-barrel; E, a pivot or bolt, on which the pulley A turns; F, the handle; H, the nut of the bolt, to which the chain 0 is fastened at the upper end of the piston-rod, to tighten the chain.

By employing acomplete pulley with the slot G through the pump-handle I am enabled to use a single wire, rope, or chain, and a single adjusting device instead of two wires, rope, or chains and duplicate adjustingdevices, heretofore employed in this class of pumps.

(No model.)

The device is cheap and simple, and its construction and operation will be readily understood from the foregoing description, when taken in connection with the accompanying drawings.

I am aware of patents to H. llosick, No. 41,298, dated January '19, 1864, and E. Glendillen, No. 173,457, dated February 15, 1876, in which a pivoted lever having a semicircular plate over which a rope or chaiirpasses, and connected to the lever and piston of a pump, whereby vibrating said lever will raise and lower the piston, and also with devices for adjusting the rope or chain; and such I do not wish to be understood as claiming broadly as of my invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is

In a pump, the combination of the pivoted pump-handle provided with the pulley A and a slot, G, the piston-rod B, having staple J and adjustable hooked bolt at the upper end thereof, and a chain, rope, or wire, 0, attached to staple J, thence passing over the upper surface of pulley through slot G, thence around the under surface of said pulley, and connected to said adjustable hooked bolt, in the manner as and for the purpose herein shown and described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

JOHN S. M. WILLGOX.
